>How do I reroll?
At the login screen sign in as a guest. play through the tutorial and use the free rolls they give you. If you don't like what you got then simply exit out of the game and repeat the process until you get what you want. Once you get something you like be sure to go to the account section in settings and bind your account, Yostar has wiped nonbound accounts in the past.
>Who should I reroll for?
The 3 best operators to reroll for on the newbie banner are Silverash, Angelina, and Exusiai, once you upgrade him to to E2 his third skill can kill a vast majority of the enemies in the game. Exusiai is also very good but her damage starts to fall off in the later chapters against enemies with high DEF. Angelina's slow and weight reduction makes her vital in a low of high level content like contingency contract.
>How should I use my originite prime?
You can use it to be skins and rolls but never use the prime directly to roll for operators. Instead you want to go to the store and look for the level up packs in the packs section of the store, you'll be getting be getting a free version and a version that costs originite every five or levels. The packs that cost originite come with the cost's worth of rolls and a ton of materials.
>Who should I E2 first?
The simplest answer will just be to E2 whatever operator you like the most, everyone (except for frostleaf) gets better at E2 by a large margin so you can't really go wrong E2ing someone you like.
>Is this operator good?
Probably yes, almost every operator is just fine with some exceptions. For example if you don't like Saria you can get by just fine using Gummy or Nearl. Though there are unredeemable shit operators like Flamebringer but they're pretty rare. You'll get by just fine ignoring the meta in everything that isn't high level contingency contract.
>Does this game have a pity system?
It has two, technically three. The first ten rolls on every banner are guaranteed to give at least one 5 or 6 star, every time you roll on a non limited banner and don't get a 6* star your chances to get a six star on the next roll are increased by 2% and is reset when you roll a six star, and finally limited banners give you a little bit of special currency on every roll that once you have about 300 or so rolls worth of you can use to exchange for the limited 6*.
>What's contingency contract?
Every few months for 2 weeks an event runs where you get access to a set of maps that you can choose modifiers for to the make the map harder and get a higher risk level, the higher the risk level the more rewards you get up to a cap of 18 on the permeant map and 8 on the daily map that changes every day.
